Takes a fitted spm object produced by
spm() and summarises the fit.
Usage
## S3 method for class 'spm'
summary(object,...)
Arguments
object
a fitted spm object as produced by spm().
...
other arguments.
Details
Produces tables for the linear (parametric)
and non-linear (nonparametric) components. The linear
table provides coefficient estimates, standard errors
and p-values. The non-linear table provides degrees of
freedom values and other information.
Value
The function generates summary tables.
